The codes for the visualizations below are in the .R file of this repository. This is my second time analyzing this type of data. The first time was more than a year ago with the data downloaded from United States Department of Labor.

Let’s plot again top 25 states hiring the most but for each year seperatly.
Visualizing top 50 cities for total certified with H-1b cases were issued between years of 2011-2016.
New York City seems to be the outlier with more than 57% difference from Houston ranked as the second city hiring the most. As we saw above, New York City alone surpases its state of New York by almost double for the total number of certified H-1B cases for all the years.
Visualizing top 25 cities for each year.
Map of top 10 states hiring the most.
Map of top 25 cities hiring the most.
Visualizing top 25 job titles for all the years together.
Visualizing top 25 job titles for each given year.
